Add missing wl_shm_pool::error enum

Browse source 
Existing implementations are using wl_shm::error for errors that apply to both
wl_shm and wl_shm_pool. The existing error values are assigned to the new
enum so existing code will continue to work but it will now be clearer what
errors can be emitted. wl_shm::error::invalid_format is now unused.
